VS 2010 Picture Box Glitch?
Jun 20, 2011
To make this simple i have a multiple forms. On form 1 is a picturebox whose image property is set through a series of case statements as follows:
If (MyImage IsNot Nothing) Then
MyImage.Dispose()
End If
Select Case cnt_ACerv
[Code]...
The issue is that whenever i navigate away from this form and then back to it the picturebox is glitched and will only appear as a white box with a red X through it. Im sure there is something simple i am missing or a refresh that needs to be done but at this point i am unaware of what to look for. I have checked the variables inside my case statements before i navigate away and after i navigate back and they appear to be correct at both points.

I have a backgroundworker that populates a dataset. My datagridview is bound to the dataset, and the datagridview refreshes once the bgworker is completed. Even after a refresh, the vertical scrollbar is missing, and clicking anywhere on the dgv does nothing. If I stretch the rightmost column to the right, the scrollbar appears and everything operates correctly.

I am just down right confused right now... I made a slight modification to my games saving system, and it worked before this modification... I only changed "one" thing in the saving and loading of the save file system.
now it went from working when trying to verify the save data, to throwing this error when I enter the username of "test" and the password of "test...
there is not a save file for that combination of data, and prior to the save/load system edits, it would realize that, and throw a message box error that I made for that senario... but now, it does this when trying to load the human class. that save file that it is trying to load and verify that does not exist is supposed to be "test the human"
"Could not find a part of the path 'F:\Ashes of Redemption\Ashes Of Redemption(01-02-2012)\Ashes Of Redemption\bin\Debug100 the 250\100 the 250.txt'."
it is supposed to throw my message box stating that there is no file in that combination, and the edits that I made only write a description of what each line of code is in the game... I had also made a variable called "nulldata" that takes those lines of text, and keeps them out of the games loaded data, so for each string of text that I added, it is basically rendered useless upon the save file being loaded...if you enter valid save information, then it loads just fine... so I am just plain confused right now.
the NEW save function'[code...]
now I am going to root around in my code now to see if I cant figure out by chance what is going on here.

The program consists of a datagridview with data loaded from our sql server.Once in a great while, the up and down arrows on the scroll bar will be blanked out and I am not able to click on them. When I try scrolling using the scroll bar, the datagridview is resized instead of scrolling.
NOTE: This isn't a program I wrote, just one that I'm using. It was developed with VB 2005 Express, framework 2.0.

In the project I am translating from vb6 to vb.net, one of the key features is in drawing various graphics like lines, circles, arcs, rectangles, etc in a Picture Box control. From what I have run into, there seems to be at least two different approaches, using WPF and GDI.

I am successfully able to pull images into a picturebox in my program and manipulate them in a variety of ways. What i need to be able to do is the following.
1) Pull images into a picture box on my main form and dynamically resize either the picture box or the image so that the image doesnt lose its scale when it comes in
2) Have a method of pre-screening an image to be loaded before it comes in so that i can change its size without losing scale .. ex.
if my image is 1200x1200 i do not have that much room on my form so i would want to say something like
if getimagewidth()>600 then
me.picturebox.width = getimagewidth()/2
end if

I have come to the conclusion that it isn't a simple 2 line code, to send a picture via a TCP/IP connection. It has to be converted to bytes, sent and received properly on the other side. In short, I've tried this, and (as you can imagine, now that I've made this thread) I failed. Here's my
Client Private Sub ConnectBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ConnectBtn.Click
If IPTxtbox.Text = "" Then
[CODE]...........
In short, I've made it possible to send strings, but... Sending Bytes and receiving them properly, I can't seem to manage.

I have two picture boxes and a timer In the timer, I have this
[Code]...
I have already got the code so I know when the picture has been changed so I don't need to do anything with that (I am pretty sure) but the big problem is that when PictureBox1 already has an Image, the next Image in the clipboard that is copied replaces PictureBox1's Image instead of going to PictureBox2. Will anyone be able to solve this?

I'm making an picture manager for personal use, and was wondering if it's possible to list up more information of an image. For instance, In Windows 7 there is a feature when I left click one time at a picture I get a little thumbnail and some information about the picture, like: Dimensions, ISO-Speed, Camera producer, blitz mode etc.
So my question is; How can this be implemented to Visual Basic 2010?

I have a picture box that is wider than the screen, with a stretched image. Can I put scroll bars on this picture box? I tried making the form as large as the picture box (which is 3840 x 2160) and then just move the form sideways by clicking and dragging on the control box, but the form will not go larger than 1940 x 1100. Can I put scroll bars on this picture box, or is there another technique I should use?

I've been trying to make a grid to test some AI stuff I'm working on. I managed to do it using rectangles and graphics.rectangle (pens.black, rect) by using a vid on youtube, but it made the application virtually useless because of all the memory it was using. I don't need it to be an actual grid, but I do need it to have values as if it was a grid, so that I can issue commands (x,y coords). (I have been searching the forums for over an hour, but all examples are either useless or cant be converted correctly).

I am trying to perform Zoom and Pan the image in Picture box using the following The Width and Height of the picturebox is (1024,1024).
Private Sub Picturebox1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Picturebox1.Paint
If Mouse_Operation = "ZOOM" then
ZoomWidth = 1024 * Total_Zoom_value
ZoomHeight = 1024 * Total_Zoom_value
[code]....
Total_Zoom_Value and (imgx, imgy) are calculated based on the mouse movements on the picturebox.Now I am able to do the PAN operation after Zoom operation. But If i try to do Zoom operation after PAN operation, I am not able to Zoom the image from the PAN co-ordinates (imgx, imgy). I am not getting how to retain the image drawn using e.graphics.drawimage.how to do the operations on e.graphics.drawimage.

studying GDI+ for drawing, there are many suggestions to expose the graphic surface for the paintbox control or a form using e.graphics in the paint event. Can graphics be exposed outside the paint for the picture box control?
In my old vb6 project that I am converting to vb.net 2010, I have several large routines located in a code module that draw lines, circles, etc on a picture box and it is desirable to keep these outside the paint event of the picture box so the same routines can be used to draw on more than one picture box.
In experimenting, I found I can create e.graphics from the picture box paint event and pass it by reference to a drawing routine and the drawing routine seems to work ok on initial experiments but it requires visiting the picture box paint event to get the drawing surface in the external sub.Is this apprach good programming practice or is there a better way to create the graphics surface of a picture box or form in subroutines outside the paint event?
